Expired Security domains with backlinks

Updated

This page lists 671 expired Security domains with backlinks. Each has expired, is available to register, has referring domains that survived the original site going offline, and was classified as Security from its archived content. Names are masked on Free; the Starter and Business plans show every name. Every metric is open.

About this list

Every listing is verified the same way as the rest of the directory. Availability is re-checked against the live DNS root over DNS-over-HTTPS, and a listing that turns out to be registered is removed. Referring domains are counted from our own web crawl, not from a paid link index. Site history comes from archived captures: the archived snapshot count and the span of years the site was captured. Revised Score blends link-graph centrality, referring domains and site history into one 0 to 100 grade, computed across the whole directory.

Category evidence exists for part of the directory, and this page grows as classification runs. Compare the Security listings on age, referring domain band, named linking sources, site history and Revised Score before choosing one.

Frequently asked questions

How do I find expired Security domains?
Browse this page. Every listing has been classified as Security from its archived content, has expired, is available to register, and has referring domains counted from our web crawl. Names are masked on Free, the Starter and Business plans show every name, and metrics are open. Starter and Business show the name; then register it at any registrar.
How is the category of an expired domain decided?
From what the site was. Each domain's archived pages are classified into one of the directory's categories, and only a confident classification is stored. A domain whose history is ambiguous shows no category and is not on this page.
Why does the category of an expired domain matter?
The topical fit is the point. Google's expired domain abuse policy targets expired domains repurposed to host unrelated content. A Security domain used for a new Security site keeps its history; the same domain used for something unrelated should not expect to.
